I just tried again with no luck. I will be taking the car in for a service before too long and will ask them. If I find out anything I will post here. I appreciate those of you that have tried to help.
I did find the so called "button". But in the back it seems to slide into the mounting and it is hard to push it in far enough. I think I probably need a small piece of wood or sometjhing that won't cut the leather to help push it in. I never got the headrest "slide" to actually release. Probably the Government is looking out for my safety
I don't know if this will help you or not. But there is a button for each post. Both buttons are on the right side of the post. The the right post can be pressed by sliding your hand in from the right side. The left, slide in from the back, this one is even harder to press
but I found that if you can get a piece of it she goes easy enough. I was able to pull both headrests right up.
